AXLE-BOX FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 442,521, dated December 9, 1890.

Application iiled July 19, 1890. Serial No, 359.287. (No model.)

T0 a/ZZ whom, 25 may concern:

Be it known that I, HENRY M. GOODMAN,a citizen of the United States, a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Axle-Boxes for Vehicles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical longitudinal section. Fig. 2 is a vertical section of a modilied form of boxing.

This invention relates to certain improvements in axle-boxes; and it consists in the novel construction and combination of parts, as hereinafter disclosed.

In the drawings, A refers to the axle-sleeve adapted to fit the bore of the hub and having one end adapted to receive the annular shoulder on the axle, the other end of said sleeve having an external screw-thread a.

B is the cap-section., having at its inner end a rim b, fitting upon the outer end of the hub and around the Opening c. In the same end of said cap-section is an outwardly-projecting screw-threaded flange (l, adapted to engage the screw-thread a of the sleeve A, thus connecting said cap-section and said sleeve together.

C is the cap, adapted to be wholly let into the inclosing cap-section B and having at its inner end an external screw-thread e, engaging the corresponding surface of an internal circular tlange f ou said section, said cap also having at the outer end of its screwthread e a circular ilange g, bearing against the flange f when the cap is screwed home and making a perfectly-tight joint thereat.

The outer end of the cap C has an angular stud or projection 7L to permit of its ready manipulation or, removal and replacement by a wrench. The filling-opening 1' of the lubricant chamber or reservoir O', formed by the cap and cap-section, is closed by the screwplugj.

This axle-box is simple and cheaply manufactured, and is readily and quickly applied to the hub, it also being capable of use on locomotives and street-cars as well as other vehicles.

In the modification disclosed in Fig. 2 the screw-threads are omitted from the cap-section and sleeve.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

l. The axle-box having the sleeve adapted to it the bore of the hub and a shoulder of the axle, and a cap-section adapted to tit the hub and engage said sleeve and the cap titting within and held to said cap-section at its inner circumference, said cap and cap-seetion constituting the lubricant-chamber, substantially as set forth.

2. The axle-box having the sleeve adapted to [it the bore of the hub and the shoulder of the axle and having a screw at one end, in combination with the cap-section adapted to lit the outer end of the huh and having around the opening in its inner end an outwardlyprojecting screw-threaded flange, and the cap having at its inner end ascrew-thread engaging an internal screw-threaded flange of said cap-section, and a flange bearing against the aforesaid flange, substantially as set forth.

In testimony whereof I atlix my signature in presence of two witnesses.

HENRY M. GOODMAN.
